CARAT OFFICIAL - How do I know my ring size?
Having trouble finding your correct ring size? It's easy to find if you know how to check.
A - USING AN EXISTING RING THAT FIT THE FINGER PROPERLY
Choose a ring that fits you well and measure its inner diameter, as shown in the following video:
Once you have this measurement, you can find your size in the chart below. Please note: your ring size may vary by approximately half a size, depending on your temperature, hydration level, hormones, etc.
If you are between two sizes, we recommend choosing the larger one.
